Abstract: The implementation of Fabry-Perot cavities in gravitational-wave detectors has been pivotal to improving their sensitivity, allowing the observation of an increasing number of cosmological events with higher signal-to-noise ratio.…
Einstein Telescope (ET) is a project of third generation gravitational wave (GW) detector with a planned sensitivity 10 times better than current detectors such as Advanced LIGO and Advanced Virgo.…
Le 22 juin 2024 à 09:00 (heure de Paris), le satellite SVOM a pris son envol depuis la Chine. Le lancement a été un succès et le satellite est en…
Abstract: The implementation of Fabry-Perot cavities in gravitational-wave detectors has been pivotal to improving their sensitivity, allowing the observation of an increasing number of cosmological events with higher signal-to-noise ratio.…
Résumé en anglais: Gravitational-wave data from interferometric detectors like LIGO, Virgo and KAGRA is routinely analyzed by rapid matched-filtering algorithms to detect compact binary merger events and rapidly infer their…
Le sursaut gamma long GRB230812B est très brillant et relativement proche (z=0.36). Cet événement a suscité un grand intérêt dans la communauté astrophysique et a été étudié dans tout le…
Résumé en Anglais: We present Fermi Gamma-ray Burst Monitor (Fermi-GBM) and Swift Burst Alert Telescope (Swift-BAT) searches for gamma-ray/X-ray counterparts to gravitational wave (GW) candidate events identified during the third…
GW170817 - GRB 170817A provided the first observation of gravitational waves from a neutron star merger with associated transient counterparts across the entire electromagnetic spectrum. This discovery demonstrated the long-hypothesized…
La Chine est une puissance spatiale rivale pour les Européens, mais cela n’empêche pas la coopération. Un satellite franco-chinois est en ce moment en cours d’assemblage à Shanghai. Il va…
